CHARLES SPIRO, OF NEW YORK, N. Y.

INKING DEVICE FOR TYPE-WRITING MACHINES.

- SPECIFICATION forming part of Letters Patent No. 355,418, dated January 4, 1887.

Application filed May], 1885. Serial No. 164,072. (No model.)

To all whom it may concern:

Be it known that I, CHARLES SPIRo, a citizen of the United States, residing at New York,

in the county of New York and State of ,New'

York, have invented certain new and useful Improvements in Inking Devices for Type- IVriters, of which the following is a specification, reference being had to the accompanying drawings.

This invention has relation to inking devices for type-writers, and has for its object the simplification of the devices for receiving and presenting in operative position the inking devices employed.

Other objects and advantages of the'invention will appear in the following description of the same, and the novel features thereof will be particularly pointed out in the claims.

In this instance I have illustratedthe application of my invention to on'ewell-known form of type-Writer; but I do not limit my invention to its application to any'particular type-writer, but reserve my right to vary the construction herein shown and described in any manner and to any extent necessary to adapt the same for use in connection with other forms of typewriters.

Referring to the drawings, Figure 1 is a plan of a type-writer provided with my improved inking mechanism. Fig. 2 is a substantially vertical section of the principal elements involved presented upon an enlarged scale. Fig. 3 is a side elevation of the principal elements in a modified form, and Fig. 4 isa plan of an inking-disk.

Like letters indicate like parts in all the figures.

A represents the impression cylinder or platen of a type-writer of that class in which said cylinder or platen is mounted in a pivoted frame-work, B, together with a guide-v roll, 0, rest D, and other well-known adjuncts for retaining the paper to be printed against the cylinder or platen, these parts being capable of alongitndinal movement along a supportingrrod, E, by means of suitable pawl-andratchet feed mechanism operated by the keys.

F represents thetop plate of the machine, having the usual opening therein, on the margin of which are mounted the type-levers G, which are adapted to be operated by rods G,

platenthat is, the point where the type comes I in contact therewithI slot the arm of the bracket, so that its attaching-screws H may be loosened and the bracket moved bodily, as desired. The inner end of the bracket is apertured to receive acolla'r or hollow shaft, I, on which is mounted a pinion, J, the collar or shaft being provided, on the under side of the bracket with a flange, I. The bore of the hollow shaft istapered to receive the tapered shank or stud K of a disk, L, so that said disk may be maintained in operative position by merely the friction of its stud K within the hollow shaft, and sothat the same may be easily removed and inserted, for a purpose hereinafter described.

M represents a rack-bar, which is secured to the under surface of the side rails of the frame B adjustably by means of slots B therein, in order that when the bracket is moved in or out the rack-bar may also be moved-to maintain its connection with the pinion in all bf its adjustments. WVhen the bracket H is supported at either side ofthe top, the adjustable attachment of the rack-bar is not necessary,as the adjustment of the bracket will in that case be in line with the rack-bar, and the pinion J will remain in mesh therewith.

Between the flange I of the collar or shaft I and the disk L, I insert a disk, N, of any suitable fabric or material which is adapted to yield or capable of yielding a color or ink when it is forced against the paper to be printed by the printing character employed. The disk N may be made of silk, linen, or other cloth, pa-

per, leather, 'or. any other material capable of performing the desired function. For cheapness I prefer to employ paper saturated with any of the well-known preparations of aniline or other suitable inks. I do not, however, broadly claim such disk.

In Fig. l the inner end of the bracket is enlarged to a disk shape, having an aperture, H through or into which the type Gr passes or enters when making an impression.

The apw or more impressions thereon.

erture H iselongated to permit of the beforemehtioned adjustment.

As thus far described it will be seen that while in the ordinary operation of a -typewriter of this class the carriage or frame B of the impression cylinder or platen and the parts mounted thereon travel from side to side of the machine, the rack-bar M, meshing with the pinion J, will cause the hollow shaft-I and disk L, together with the paper or inking ma terial secured between the same, to rotate, so that a new surface is exposed after each one The bracket and inking devices being supported upon the top of the machine, while the rack-bar is supported upon the pivoted, frame, permits of an elevation of said frame for the purpose of inspecting the work, as is necessary in this class of machines.

The advantages secured by rendering the bracket and rack-bar adjustable are now apparent, in that, supposing the adjustment to be such as to bring the type in contact with the inking-disk near its periphery,a slight adjustment of the bracket and rack inwardly will bring the type in contact with the disknearer its center,and this being repeated, each disk is rendered serviceable for a longer period of time than if the parts were not rendered adjustable; This advantage resulting from the adjustment is a feature of my invention to which I do not limit it, as,by reason of the excessive eheapness of the inking-disks, the adjustable feature may be dispensed with.

Vhere exceedingly light material is employed in the inking-disks I may provide in the under surface of the end of the bracketa groove, 0, or other form of construction which shall serve to support the edgesof the disk and yet permit of its rotation to present new surfaces for use.

In Fig. 3 I have illustrated a modification, wherein the disk form of the bracket is discarded, by reason of the fact that the disk 'N, which holds, supplies, or acts as the inking material, is of suificient substance and rigidity to maintain its form without the aid of external supports. As an example of such a disk I may mention a close-textured absorbent paper. The disk N is centrally apertured, as at N, to permit the passage therethrough of the stud K, in order that it may be secured in operative position by removing the stud and the disk L from the hollow shaft and returning them to position after the disk has been placed against the flange of the shaft-an operation which is readily performed by raising the frame upon its pivot, as when inspecting work.

The disk employed may be coated instead of saturated with any suitable ink.

I am aware that fixed inking-pads over which printing characters are moved and subsequently passed through an opening in said fixed pad to make an impression have heretofore been employed in type -writers; but such pads have not been movable after each impression to present new inking-surfaces, nor have said pads been provided with an aperture by which they are adapted to be mounted on a rotary device for presenting new inkingsurfaees. Ihe well known inking ribbons have heretofore been mounted to be moved longitudinally after each impression of the type thereon; but such construction requires more space, more complicated mechanism, is less convenient and tidy, and more costly than my mechanism for supporting and rotating the disk.

I do not claim, broadly, the combination, with the plateii of a type-writing machine, of a rotatable ink-disk interposed between the platen and type.

Having described my invention and its op eration, what I claim is 1. The combination, with the platen and the type of a type-writing machine, of arotatable inking-disk removably supported between the type and the platen, substantially as specified.

2. In an inking apparatus for type-writing machines, the combination of a centrally apertured absorbent ink-disk with a disk-supporting stud having a pinion, a rack, and a hollow shaft, whereby the disk may be supported inoperative position and rotated, substantially as specified.

3. The combination of an apertured inkdisk, a hollow shaft, a disk provided with a stud inserted in'the shaft, a pinion rigidly mounted upon the shaft, a supporting-bracket mounted on a fixed part of a type-writing machine, and a raekbar mounted on a moving part of the same, substantially as specified.

4. The combination of the bracket H, provided with the slots H H, the hollow shaft I, provided with the flanges I and pinion J, the tapered lug K and disk L,.the disk N, the rack-bar M, and the slotted frame B, substantially as specified.
